STEM-WINDING WATCH.

SPECIFICATIGN orming'part of Letters Patent No. 677,151, dated J' une25, 1901. Application iiled July 13, 1899. Serial No. 723,722l (Nomodel.)

i tails of construction set forth in the following specification andclaims and illustrated inthe annexed drawings, in which- Figure 1 is aplan View of the watch-movement. Fig. 2 is a section along w Fig. 1.Fig. 3 shows a modification. Fig. 4 is a detail sectional view of Fig.3. Fig. 5 shows two views of a transmission-piece. Fig. 6 Vis an edgeView of the movement.' Fig. 7 shows two views of a modication in thetransmis-y sion-piece. Fig. 8 is an inverted plan view of Fig. 1. Fig. 9is a detail view. Fig. 10 is an edge view of Fig. 9. Fig; 11 is a planof the supporting-plate 1, hereinafter described. Fig. 12 is an invertedplan of an auxiliary plate or bridge-piece la, that-is detachablysecured to the under side of a portion of the main supporting-plate.

In the drawings is shown a plate 1 of a watchmovement having a cut-outportion or seat. A `filling-plate 3, Figs. 1, 2, and 3, is made to sitor has a depending portion or lange made to tit or sit into thiscut-out. This plate 3 carries three bridges 5, 6, and 7, Figs. l, 8', 9,and 10. The bridge-piece 5, in connection with plate 3, forms bearingsfor the axle or staff of the balance-wheel 8. The bridge-piece 6, withplate 3, carries the fulcrum of the lever or anchor 9, Figs. 8, 9, and10, and between the bridge-piece 7 and plate 3 is mounted or journaledthe escapement 10. By removing plate 3, with bridges 5 to 7, includingescapement-movement 8 to l0, the escapement can be readily finished orrepaired, after which the plate or inset 3 can be replaced in thewatch-movement. A screw or fastening 11, Fig. 3, can be made to secureinset 3 and to hold or set the pinion onthe axle of escapement-wheel 10into proper mesh or adj ustment with the train-wheel12, Fig. 8. Theplate 1 being suitably recessed or sunk for seating the screw 11, thelatter will not pro-4 ject or interfere with the watch-movement or plate1 being put in its case. Iwould have setting mechanism is formed by yoke14, Fig.

1, having intermediate wheel l5 engaging winding-wheel 16 andsetting-wheel17. This mechanism is normally in winding position, as thespring 18 tends to hold winding-wheel 16 to the winding gear or drum 19and to keep the setting-wheel17 out of action or clear from the dial orhand wheel 20. A lever 21 is shown with three arms 21a, 2lb, and 21C.When the le-l ver-arm 215L acts against the yoke 14 with sufficientforce toovercorne the action of spring 18, the setting-wheel 17 isbrought into action, and the winding-wheel 16 is now idle, as seen inFig. 1. This lever-arm 21a is exposed to the pressure or action ofspring 22, which forms practically an arm of lever 23, fulcrumed at 24.rThe lever-arm 23 has a projecting piece 25, and when the watch-movementis put in the case the lever-arm or spring 22 is pressed inward, andbeing stronger than spring 18 this spring 22 will -move the yoke 14 tosetting position. The lever-arm 21b sits against shoulder 26 ofy atransmission piece or stem 27, Fig. 5, having a non-circular seat 28,Fig. 6, to which is tted the stem 29, Fig. 2, having the button or crown30, so that rotation of stem 29 is communicated to transmission-piece27. When the button 30 is pressed inward with the transmission-piece 27,the latter, by its shoulder 26, acts on leverarm 2lb to move lever-arm2la against the action of spring 22 or away from yoke 14. The yoke beingnow free from lever l21 is moved by spring 18 to normal or windingposition. When the stem 29 is drawn or snapped outward to relieve thearm 2lb, the spring 22 moves lever-arm 21a, with yoke14, to settingposition.

When the watch-movement is taken out of the case, the lever 23 or itsnose 25 is freed from confinement against the case. At the same time,the stem 29 remaining in the case, the transmission-piece 27 and lever21 are freed from such stem 29. The spring 3l, acting against the thirdlever-arm 21,now moves the lever-arm 2la away from yoke 14, leaving thelatter free to move to normal or winding IOO v rates a gear 32, whichengages yoke-gear 15.

The rotation of button 30 and stem 27 is thus transferred to gear 32 andthence to gear l5.

The transmission-piece 27, it is noted, has

kbut one shoulder 26, which sits outside of lever-arm 2lb. Whenthewatch-movement is out of the case or clear of stem 29, thetransmission-piece 27 can be slipped out of its seat 27 withoutdisturbing the lever 21. This seat 27a for the transmission-piece 27 isformed partly in the main plate 1, as shown in Fig. 11, and partlyin thedetachable piece or plate 1a, Fig. 12, which is secured to a por- 'tionof the under side of said main plate.

Loss or accidental removal of the transmitter 27 can be prevented by alock or screw 33, Fig. 6, having its head projected into or partlyacross the seat of the transmitter.Y A

vmutilated head for screw 33 is practical, as in that case a partialturn of the screw will'sufice to bring the cut or the complete part ofthe screw-head to the seat of piece 2 7 to release or contine thevlatter. Of course the piece 27 is rotatable and has enough play torespond to the longitudinal movements of the stem 29. The seat 28 andpiece 27 are of such length that in case independent longitudinalmovement of these parts occurs at any moment the engagement of piece 27with stem 29 or with gear 32 is not broken.

The device can bemoditied. In Fig. 7 the transmission-piece 27 engagesor sits through a gear'32, having seats or sleeves 34 and 35, the piece27 having a pin 36, preventing this piece being moved out of gear 32',while free to. move longitudinally independently of this 1er having itshigh part bearing against the arm 23 to move spring 22inward will causesuch spring to move the yoke to setting position the same as when thecase contines the piece 25 in inward position. The eccentric 25' ispractically connected to or forms part of the shank of one of the screwsor heads 37, Fig. 4, serving to secure the plate 1 in the case. Theconstruction shown is such that Whenthe head 37 is turned to fasteningor locking vposition the eccentric 25' is moved to hold spring 22 andlever 21 to yoke 14, so that the latter moves to setting position. Themovement is thus in winding position no matter Whether in the case orout of the case and is not brought to setting position until thefastening 37 is moved to locking or engaging position. Y

The springs 22 and 31, as seen, act in op. posite directions, one of thesprings tending accessible, so as to facilitate repairs, cleaning,

and adjusting.

Since only one shoulder, as 26, is required to actuate the lever 2l, anystem with a shoulder, such as found in the market already adapted tocases, can serve to wind and set without using the transmission piece 27. When the transmission-.pin 27 is removed,

its seat 27a in plate 1 and piece'or plate -1a give 'access to such acase-stem as justdef. scribed.

When the spring 22 moves lever21a to the winding and setting mechanism14, the spring 31 is thereby put under tension or its tension isincreased, so that ywhen the lever is again free from the action ofspring 22 the spring 31 will promptly move such lever out ofiaction orrelieve the yoke 14 from the actionof such spring.

What I claim as new, by Letters Patent, is-

1. A stem Winding and setting mechanism having a transmission-piece 27providedwith a single shoulder, a lever engaging said shouland desire tosecure der. only at the inner sideor face and leaving Ice directlyengage the lever, one of the springs being made to throw the lever tothe shoulder and thev other to throw the Ylever from the shoulder,substantially as described.l

2: A winding and setting mechanism,- a spring for normally holding the.mechanism in winding position', a lever, and springs separate from thefirst-named spring and made to engage the lever to respectively'move thelatter into. and out of action, substantially as described. Y

,-3. A windingand setting mechanism norg mally in winding position, alever, springs for actuating the lever in opposite directions, and anactuating-piece 23 made tov move one of the springs to carry lthe leverand mechanism to setting position when the movement is in thecase'substantially as described.

4. A Winding and setting mechanism, a spring for said mechanism, alever, springs independent of the first-named spring for actuating thelever in opposite directions, and an actuating piece 23 made to move.one of said springs to carry the lever mechanism to setting positionand at the same time in crease the tension of the other spring,substantially as described.

5. A watchmovement having a winding and setting mechanism normally inwinding 'Iio actuating said arm 23, substantially as de= scribed.

S. A Winding and setting mechanism and an actuating-lever therefor,combined with a swinging piece or arm 23 and a spring for moving thelever to bring the mechanism to setting position, and a fastening 87 foractuating said arm 23, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of tworsubscribin g Witnesses.
